Bartholin's cyst is a common disease of gynecology. It is cystic expansion of the gland tubes, which is caused by scar and infection. Forty years ago this disease was completely cut away by operation. In 1966, someone thought that cystostomy was a certain treatment method. Although there are many therapies used to treat this disease, e.g., incision drainage, excision, puncture, etc., they all have a better or worse side. In the past two years we used CO2 laser to treat patients in our hospital. Comparing outpatients with inpatients, the writer thinks that inpatients treated with laser (CO2) have less bleeding, less pain, faster recovery, and a higher success rate. This operation is done in the clinic and its both convenient and cheap. This method is one of the valuable methods which is worth spreading. From April 1989 to April 1991, 74 patients were treated with traditional operation and drug treatment. Another 38 patients were treated with the laser in the clinic. Clinical treatment results are contained here.
